Apple on Thursday seeded the second beta of OS X Yosemite 10.10.5 to developers. The software, labeled build 14F19a, is available to all registered Mac developers in the Updates section of the Mac App Store, or as a standalone download from Apple’s dev portal.

Beta 2 of 10.10.5 comes two weeks after the first developer beta, and just a month after 10.10.4 was released to the public. It also comes on the same day as beta 2 of iOS 8.4.1, suggesting that Apple is looking to shore up its two OSes before their major fall updates.

With that in mind, we don’t expect to see any new features in 10.10.5. Apple essentially confirms as much in the release notes, saying “the OS X Yosemite 10.10.5 update improves the stability, compatibility, and security of your Mac.” We’ll let you know if that changes.

Earlier this week, Apple seeded beta 5 of OS X El Capitan to developers, and a public release is expected within the next few months. That update will include a handful of user-facing features, but will also focus on reliability and other performance-related improvements.
